Answer 1

Does your program work on your own computer?

Read your runtime error. The gnuplot executable is not found.

gnuplot is a linux utility that must be installed separately.
http://www.gnuplot.info/

The ruby gem 'gnuplot' is only a wrapper for this, it depends on the existence of pre-installed gnuplot.
You can see installation instructions here:

I think this is not going to work on Sololearn.
